低层冷弯薄壁型钢房屋振动台试验及有限元分析
|
摘要
为研究低层冷弯薄壁型钢房屋在地震作用下的动力特性,对一个原大的三层冷弯薄壁型钢房屋模型进行了振动台模拟地震试验;根据试验结果分析了该结构体系在地震作用下的破坏特征和动力特性,应用有限元分析程序建立了简化模型,并对模型结构进行了计算分析;最后对该结构体系的研究方向和结构设计提出了建议。结果表明:位移反应的计算值与试验值吻合良好,该结构体系是一种理想的新型抗震结构体系。
In order to study the dynamic characteristics of low-rise cold-formed thin-walled steel residential buildings under earthquake,a shaking table simulation seismic test was carried out for a 1∶1 scale three storied cold-formed thin-walled steel residential building model.The damage features and dynamic characteristics of the prototype structure were got by the similitude relationships according to the testing results.Using finite element analysis programs,the simplified model structure was made.Finally,some advices on research and design for this structure system were put forward.The results show that the calculated values coincide with the test values.This kind of structure system is a new ideal aseismic structure system.
